Dionex IonPac ATC 500 阴离子捕获柱 | 079018,075976
Anion Trap Columns 阴离子捕获柱Dionex IonPac 阴离子捕获柱含有高容量的阴离子交换树脂。阴离子捕获柱安装在洗脱流路的进样阀前,能避免梯度淋洗时淋洗液中的会产生假峰的污染物。Dionex ATC 阴离子捕获柱含高容量、低效率的阴离子交换树脂,以去除氢氧化物淋洗液或硼酸盐淋洗液中的痕量阴离子污染物使用 Thermo Scientific Dionex IonPac ATC-3 和 Dionex IonPac ATC 500 阴离子捕获柱,可除去氢氧化物或硼酸盐淋洗液中的痕量阴离子污染物。这些捕获柱安装在进样阀之前、泵之后的淋洗液流路中,可避免在梯度操作期间生成假峰并尽量减少基线漂移。Dionex IonPac ATC 500 与 Dionex IonPac ATC-3 完全相同,但其包裹在柱体内,支持在高达 5000 psi (34.5 MPa) 的压力下连续运行 Thermo Scientific Dionex HPIC 高压离子色谱系统。经过工程设计,可达到卓越的色谱分析性能1.5meq/柱容量 (4mm)0.35meq/柱容量 (2mm)4 ' 35mm 规格,适用于 2mm 和 3mm 应用9 ' 24mm 规格,适用于 4mm 应用定期离线再生可延长使用寿命关于阴离子捕获柱Dionex IonPac ATC 和 Dionex IonPac ATC 500 阴离子捕获柱包含水合氢离子型微孔阴离子交换树脂。阴离子捕获柱可去除淋洗液和/或去离子水中的痕量阴离子污染物,避免它们进入保护柱或分析柱。淋洗液和/或去离子水中的阴离子污染物往往会干扰痕量阴离子测定的精度,执行涉及梯度淋洗液的阴离子交换应用时尤为如此。 Dionex IonPac ATC-3 and ATC 500 Anion Trap ColumnsThe Thermo Scientific™ Dionex™ IonPac™ ATC-3 and ATC 500 Anion Trap Columns contain a high-capacity, low-efficiency, anion-exchange resin in the hydroxide form. The columns strip trace contaminants from hydroxide or borate eluents. The traps are installed in the eluent line prior to the injection valve to prevent spurious peaks during gradient chromatography and to minimize baseline shifts during gradient operation. In an RFIC-EG system the traps can be placed between the Thermo Scientific Dionex EGC cartridge outlet and the injection valve. In this configuration the Dionex IonPac ATC-3 and ATC 500 are ideally suited to gradient RFIC-EG eluents due to their low dead volume. The Dionex IonPac ATC 500 supports HPIC™ system pressures up to 5000 psi (34.5 MPa).IonPac ATC Anion Trap Column SpecificationsATC 500 SpecificationsDimensions9 × 24 mm (4 mm applications)4 × 35 mm (2 mm applications)Mobile phase compatibility0–50% HPLC solventsSubstrate characteristicsBead Diameter: 55 μmCross-Linking (%DVB): 8%Functional group characteristicsIon-Exchange Group: Quaternary ammoniumHydrophobicity: LowCapacity1.5 meq (9 × 24 mm, 4 mm applications)0.35 meq (4 × 35 mm, 2 mm applications)Max.
